Card 95 / 153: A researcher wants to prove that structural family therapy is the most effective modality. She conducted a study a year ago using a signifi cance level of .05. Several colleagues felt her signifi - cance level needed to come down. She thus ran the same basic experiment again with new people using a signifi cance level of .01. Her chances of making a Type I error or so-called alpha error went down. Now assume you compare her new research with her old research. What could you say about the possibility that her results will indicate that structural family therapy was not signifi cantly different when in reality it truly is signifi cant?
A) Statistically, nothing
B) The chance of this occurring will go down when compared to the fi rst experiment.
C) The chance of this occurring increases when compared to the fi rst experiment.
D) It would totally depend on the sample size.
